Oasi Bosco di San Silvestro, Nature reserve in Caserta, Italy.

Oasi Bosco di San Silvestro is a nature reserve near Caserta spanning roughly 76 hectares across two connected hillsides. The woodland is covered in Mediterranean plants such as holm oaks, downy oaks, hornbeam, and laurel trees that are native to this region.

The San Silvestro estate was assembled from lands bought after 1750 and united into a single holding enclosed by a perimeter wall, parts of which still stand. It was one of the Reali Delizie of the Bourbon court, alongside San Leucio and the Royal Park, and was used for farming and hunting. Between 1797 and 1801 the architect Francesco Collecini built the Real Casino di S. Silvestro on the Parito site.

The estate kept the Vigna del Ventaglio, a fan-shaped vineyard where, under the Bourbons, every grape variety grown in the kingdom was planted. Olive groves, orchards and vegetable gardens also surrounded the woodland. The name San Silvestro comes from the estate's dedication, not from a local cult.

The reserve is best explored during daylight hours when the trails are clear and nature is most active. The grounds have marked pathways, though sturdy footwear and basic fitness help if you plan to walk both hillsides thoroughly.

The Vigna del Ventaglio, a fan-shaped vineyard, held every grape variety grown in the Bourbon kingdom. Allied troops occupied the estate during World War II, and concrete platforms laid for tracked vehicles crossing the wood are still almost entirely covered by vegetation.
